The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, 3, the structure of erecting tools of the present invention is, comprises flange 4, and flange 4 is equipped with lifting sub 5 along the axle center, flange 4 upper surfaces are provided with two hydraulic cylinder assemblies 2, and the holder of hydraulic cylinder assembly 2 is fixedlyed connected with flange 4 upper surfaces by little dormant bolt 3; The circumferential end surfaces of flange 4 is equipped with guide cylinder 9 downwards, guide cylinder 9 is fixedlyed connected with flange 4 by dormant bolt 1, guide cylinder 9 peripheries are consistent with flange 4 peripheries, be set with between the inwall of guide cylinder 9 and the flange 4 and drive tube 8,9 pairs of guide cylinders drive 8 guidings of tube and supporting role, drive tube 8 and are connected with the piston rod of two hydraulic cylinder assemblies 2; The waist excircle of flange 4 has rotation slot 15, is provided with ten cat's paws 6 between rotation slot 15 and the driving tube 8, and flange 4 positions of each cat's paw's 6 top correspondence are equipped with a pin 7.
With reference to Fig. 2, the inwall that drives tube 8 is arranged at intervals with ten raised lines 12, and all raised lines 12 are positioned on the same periphery, are breach 11 between the adjacent raised line 12, and the piston connecting hole 19 on the driving tube 8 is used for connecting the piston rod of hydraulic cylinder assembly 2.
With reference to Fig. 3, each cat's paw 6 upper end is provided with towards inner headed face and rotates plush copper 16, rotates plush copper 16 and is installed in the rotation slot 15 of flange 4, and cat's paw 6 upper ends are towards being outside equipped with sharp mouth 20, be used for passing through at the breach 11 that drives tube 8, and with raised line 12 kaysers that drive tube 8; Cat's paw 6 upper ends are provided with sliding tray 14, are used for the swing with the pin 7 common cat's paws 6 of realization; Cat's paw 6 excircle epimere is provided with groove 13, realizes being slidingly connected with the raised line 12 that drives tube 8, and cat's paw 6 lower end inwardly is provided with cat's paw's hook 17, is used for realizing that with the equipment link slot 18 of equipment connector 10 hook is connected.
With reference to Fig. 4, erecting tools of the present invention is when assembling, and at first in ten screwed holes with ten pins, 7 whole precession flange 4, the swing that pin 7 is mainly cat's paw 6 produces guide effect.Then respectively cat's paw 6 is respectively charged into corresponding rotation slot 15 positions of each pin 7, and cat's paw 6 can rotate flexibly, make it be adjacent to the face of cylinder, lower end of flange 4, to drive tube ten breach 11 of 8 then and align empty place between each cat's paw 6, after it was inserted in along axis, rotation ten raised lines 12 driving tube 8 entered into the groove 13 groove face positions at cat's paw 6 backs again.Then, with the piston rod of 2 hydraulic cylinder assemblies 2 being symmetrically distributed with drive tins 8 and be connected, use little dormant bolt 3 symmetrical fixer cylinder pressure assembly 2 on flange 4 respectively simultaneously, use dormant bolt 1 fixedly connected guide cylinder 9 again, at last lifting sub 5 is screwed in flange 4 screwed hole of centre, then install and all finish.
Cat's paw 6, pin 7 are corresponding one by one with the quantity of raised line 12.Cat's paw 6 quantity can or be that other are a plurality of for illustrated ten.It is whole for diagram to drive tube 8, or divides body structure for multi-disc.Pin 7 is that cylindrical structural or head are the structure of spherical or other camber line shape.Hydraulic cylinder assembly 2 is one or more quantity.
The course of work of erecting tools of the present invention is:
1) in implementing kit and equipment connector 10 connection procedures, at first the pin thread with hanging device is connected with the box of lifting sub 5 upper ends, perhaps elevator is connected with lifting sub 5 upper end necks, then this instrument is vertically transferred to the place, plane, upper end of equipment connector 10, cat's paw's hook 17 of cat's paw 6 and the equipment link slot 18 groove faces location on the equipment connector 10 are aligned, the rodless cavity oil-feed of hydraulic cylinder assembly 2 at this moment, then the piston rod of hydraulic cylinder assembly 2 moves downward, driving driving tube 8 moves downward, driving tube 8 continues to move downward under the guide function of guide cylinder 9, boss on the driving tube 8 progressively pushes groove 13 groove faces at cat's paw 6 backs, its cat's paw 6 is being had mercy on to rotate with the contact point of flange 4 troughs, driving tube 8 continues descending, then cat's paw 6 is rotated further, and when cat's paw 6 forwards to when parallel with axis direction, it stops operating, cat's paw's hook 17 of cat's paw 6 embeds in the equipment link slot 18 of equipment connector 10 fully, thereby realizes being connected of apparatus of the present invention and equipment connector 10;
2) in implementing kit and equipment connector 10 disconnecting process, the rod chamber oil-feed of the hydraulic cylinder assembly 2 of this invention, then the piston rod of hydraulic cylinder assembly 2 moves upward, driving driving tube 8 moves upward, when each raised line 12 that drives tube 8 contacts with the sharp mouth 20 in cat's paw's 6 back grooves 13 groove faces upper end, it drags cat's paw 6 lower ends and outwards rotates, thus the equipment link slot 18 of cat's paw's hook of cat's paw 6 17 release apparatus connectors 10, and finally realize the release disengagement.
Erecting tools of the present invention utilizes hydraulic jack directly to drive the driving tube and moves downward, and inwardly swings by the locus of design by each boss extruding cat's paw mechanism of its circle distribution, reaches locked state; Utilize the hydraulic jack counter motion simultaneously, to drag the outside backswing in cat's paw lower end, reach the purpose of its complete release apparatus connector.Apparatus of the present invention compactness rational in infrastructure, simple has simple operation, connects reliably, carries evenly.
